I recently bought some "KO micro blocks" sets from "Daiso" in Japan. These are great value and very poseable. They are also only ¥100 (about a dollar) there. They've got all kinds of models, including cute animals, dinosaurs, Samurai and also these robot ones. They're are also two transforming ones, which I've still to make at home. I'm post pics of the transforming ones at this thread later, as I'm not sure if there's another more suitable place for them. Please let me know if there is an alternative, however. Regardless, I totally recommend these as cheap, good quality toys to quickly build, pose and relieve some stress.
A video playlist, showing quick builds of the entire set of the "Robot Builder's" (sic) line, can be found here:

Also, a young lad had got a vid of the full set here:
